    There's a tool that you attach to a cap tube and push it out with thousands of psi with oil or solvent. It's pressurized with a screw down oil pump or hand driven hydraulic pump.

    It was in the same refrigeration and HVAC book that talked about cutting open a hermetic compressor for repair.

    Yep and it's called CAP-CHECK m#1003 by Thermal Engineering
    Also check out the CAP-CHECK CHASER KIT m#1101

    Easy to say, but when there is no space to move around in and the cap tube is brazed to the suction line from beginning to end having more options is always nice.

    have used R409A and R401A without changing TXV. both work fine

    Changing the cap tube is still the best option since you're assured of "fresh from the factory" passage of refrigerant. If they brazed the cap tube to the suction line as a heat exchanger, duplicate it by making a new line set. The cap tube doesn't need to be brazed to the suction line. Soldering the lines together will serve the same purpose, requires less heat and far easier to apply.

    By the time you're done fiddling around with that cap tube cleaner widget, I've got 2 of them done and I'm off on a third call.

    Yeah that widget does look like a glorified bottle jack for a lot more money
